Check this month's numbers before you fileSign-ups are not open yet. We counted that someone asked — not who, and not which permit — and we open them once enough people do. The check stays free.
Last period with anything received: 2026-07-31. Most often over: Oxidants, total residual (6), Velocity of intake (5), Flow, in conduit or thru treatment plant (3).
Reports are due about 15 days after each monitoring period ends (read off this permit's own late-day counts in EPA's filings).
